Software Composition Analysis Audit

Scan dependencies for known CVEs by following the full procedure in plays/sca-audit.md.

Steps

1. Identify Dependency Manifests — Scan for all dependency files and lockfiles across ecosystems (Node.js, Python, Go, Java, Ruby, Rust, .NET, PHP). Prefer lockfiles for exact resolved versions.

2. Run Vulnerability Scan — Use available tools in preference order:

   • osv-scanner --lockfile=<path> --format=json (recommended, multi-ecosystem)
   • npm audit --json (Node.js)
   • pip-audit -r requirements.txt --format=json (Python)
   • govulncheck ./... (Go)
   • trivy fs --format json --scanners vuln <path> (multi-ecosystem)
   • If no scanner is installed, stop and ask the user to install one (e.g., brew install osv-scanner). Manual analysis is not viable — even small projects have 50+ dependencies. For individual package triage, point the user to OSV.dev.

3. Analyze Results — For each vulnerability: determine reachability (is the vulnerable code path used?), check exploitability context (deployment matters), and identify fix availability (patch vs major version bump).

4. Dependency Health — Beyond CVEs, flag unmaintained packages (2+ years inactive), typosquatting risks, license concerns, and version pinning issues.

Output

Scan summary (ecosystems, dependency count, scanner used), findings sorted by severity using templates/finding.md, condensed table for medium/low, dependency health flags, and exact remediation commands.
